Has anyone ever used 6mm apex seals?
I found this engine builders site. They're in Canada. They say they can use an apex seal up to 6mm thick. Anybody have first hand experience with these.

Everyone who had a '73 and earlier Mazda rotary had 6mm apex seals.
6mm one piece carbon-aluminum. They were much of the reason why rotaries had a reputation for no low-end torque and poor longevity.
Mazda figured out how to make iron work for apex seals and introduced them for '74. They were 3mm for less friction, and two piece for better sealing. Longevity problems *eliminated*.
Later they went one better and made three piece, 2mm seals, for even less friction, even better sealing, and even longer rotor housing life.
Then they put turbos on the things are destroyed all that hard work in proving the engines' longevity.
